APPABATUS FOR APPLYING POWDER IN MANUFACTURING ARTIFICIAL STONE.

SPECIFICATION formingpart of Letters Patent No. 628,317, dated July 4, 1899.

Application filed December 8, 1898. Serial No. 698,646. (No model.

To all whom it may concern.-

Be it known that I, GUsTAv HATTINGEN, manufacturing director, a subject of the King ofPrussia, German Emperor, residing at Sinzig, in the Kingdom of Prussia and German Empire, have invented certain new and useful Improvements in Apparatus for Use in Applying Powderin the Manufacture of Artificial Stone or the Like, of which the followingis a specification.

My invention relates to improvements in or relating to apparatus for use in applying powder in the manufacture ofartificial stone or the like. Heretofore brushes, pencils, orother tools have been used'for the introduction of powder or paint in the form of powder into compartments or molds, used in the manufac-i ture of compressed stones or the like to which a pattern or design is given, which tools pushed the material through stencils. The pencils or pins were sometimes surrounded with springs, which owing to their mobility during the reciprocating movement of the holders prevented the powdered material from forming into lumps.- These devices suf fer, however, from the drawback that in their downward movement the pins enter the openings of the stencil-plate, whereby a certain amount of pressure is exercised on the powder. Such a pressure, however, results in the powder forming lumps on the stencilplate, and thus clogging its openings. These drawbacks are obviated by the invention forming the subject of this application, according to which wires or metal rods are provided at their lower ends with bristles forming brushes having the shape of an ordinary painting-brush. In their descent the bristles v spread outward and-extend horizontally over the openings of the stencil-plate, so that they do not exercise any pressure on the powder mass. The success attained with such brushes spreading out in their descent may be rendered more complete by arranging the bristles horizontally or at right angles to their holders, and thus preventing them from exercis-,

ing any vertical pressure-on the loose mass of powder situated under them.

In the accompanying drawings, Figure 1 is a vertical longitudinal sectional view of an apparatus embodying my invention. Fig. 2 is a detail transverse [sectional view through one end of the base portion of the apparatus; and Figs. 3 to 7, inclusive, are diagrammatical views showing the brush-bristles arranged at rightangles to or radiating from their carryingrods or wires.

The apparatus consists of a. paint or powder reservoir 1, the detachable bottom'of which constitutes a stencil-plate 2, provided with openings 3, arranged according to the pattern to be produced on the blocks. The reservoir is divided into a number of compartments 4 for receiving different kinds or colors of paint or powder, in which compartments are arranged rods 6 or wires 5, provided with metal or other bristles. The rods 6 consist, preferably, of helically or otherwise bent strips of metal or twisted, perforated, ornon-perforated metal strips or rods andfc-arry at their lower ends the metal or other bristles forming the brushes 7. The brushes are so distributed overthe wires or rods that intervals :0, Figs. 3, 4, and 5, are left, in which the powder can collect, said accumulation of powder being, however, disturbed during the vertical reciprocating movement of the strips or wires, so that the'mass is continually maintained in a loosely-aggregate condition. The powder is not forced through the openings 3; but, on the contrary, the bristles spread outward over the openings 3 in the descent of the brush, and allow the powder resting on them to sift through during the reciprocating movement. This reciprocating movement of the wires 5 or rods 6 is effected by means of a lever 8. Owing to the shape of the wires or rods the material is kept continually on the move. The formation of lumps is thus made impossible; but, on the contrary, the powder is uniformly fed downward.

The result obtained by means of the brushes described is rendered considerably more perfect if the end bristles are arranged at a right angle to or radiate from their support,whereby they are prevented from exercising a vertical pressure on the loose material 'under them. When pushed downward, the bottom or lowermost brushes spread outand close the openings 3 of the perforated bottom 2 against the material above them.

The more frequent the shaking or reciprocating movement the greater will be the amount of material supplied to the mold cells or chambers 9. Vhen the necessary amount of material has been supplied, the upper part of the device resting on the plate 10 is lifted off by means of levers ll, 12, and 13 and the mold 14 situated under it removed and filled with the composition from which the artificial stone or material is to be produced. The mold is then removed and placed in the press.

The levers are arranged in a box or casing 15,formingthe base of the apparatus,and comprise levers 11, 12, and 13, arranged at both ends or sides of the apparatus, the levers 11 and 13 being secured to rods 16, rotatably mounted Li the box 15 and operated by means of a treadle or lever 17. On each of the central horizontal levers 12 rest two blocks or projections 18 and 19 of the plate 10, guided in correspondingrecesses 20 in the box 15.-

By suitably operating the treadle or lever 17 the blocks 18 and 19 may be either raised or lowered and the whole device correspondingly raised and lowered.

Having now particularly described and ascertained the nature of my invention and in what manner the sameis to be performed, Ideclare that what I claim is 1. In an apparatus for introducing powder into molds in the manufacture of artificial stone, or the like, the combination with the powder-reservoir, the stencil-plate in the bottom thereof and the mold under the stencilplate, of vertically-movable rods orwires having bristles at their lower ends which, when the rods or wires are lowered, spread horizontally over the upper surface of the stencilplate, substantially as and for the purpose described.

2. In an apparatus for the manufacture of artificial blocks, by introducing powdered material into molds, the combination with a powtier-reservoir, a pattern stencil-plate in the bottom of the latter, and a mold beneath the stencil-plate, of vertically-movable rods havin g bristles whicl1,when the rods are depressed to force the powder through the pattern-perforations of the stencil-plate, stand substantially parallel to and press upon the upper surface of the stencil plate without entering the pattern-perforations thereof, and means for depressing said rods, substantially as and for the purpose described.

3. In an apparatus for introducing powder into molds, in the manufacture of artificial blocks, the combination of a reservoirdivided into separated chambers for differently-colored powders, a pattern stencil-plate in the bottom of said chambered reservoir, rods having bristles for opening and closing the pattern perforations of the stencil plate, and means for raising and lowering the said rods, substantially as and for the purpose described.

4. In an apparatus for introducing powder into molds, in the manufacture of artificial blocks,the combination of a powder-reservoir, a pattern stencil-plate in the bottom of the reservoir, bristles for opening and closing the pattern-perforations in the stencil -plate, a mold under the latter, a lift-plate on which the powder-reservoir rests, lift-blocks bearing against the lift-plate, pivoted levers supporting the lift-blocks, and means for rockin g the levers to raise and lower the lift-blocks, lift-plate and reservoir, substantially as and for the purpose described.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit- HGSSGS.
